Detective Tyler

Detective Tyler was strolling one day, when he saw an old friend of his, Michael. "Hey Tyler! Long time, no see," said Michael. "Anyways, the Super Bowl is on Sunday. I, as a Pittsburgh Steelers fan, wanted to see them defeat the New England Patriots! I was wondering if you could let me borrow the money to go see the game."
"Come up with a better lie, and maybe I'll believe you next time," said Tyler.

How did Tyler know that Michael wasn't going to use the money to see the Superbowl?
